UNITED` STATES MENDEL SCHWARTZ, 0F BROOKLYN, NEW YORK.

PORT-LIGHT.

Application led December 2, 1919, Serial No. 341,856.

T 0 @ZZ whom t may concern Be it known lthat I, MENDEL SCHWARTZ, acitizen of the United States, residing formerly in the city and countyof Philadelphia, State of Pennsylvania,now residing at Brooklyn, in. thecounty of Kings, State of New York, have invented a new and usefulPort-Light, of which the -following is a specification.

My invention consists of a port light which is constructed ofinterfitting ring-like outer and inner members which are connectible bya movable oint which also permits the disconnection of said members, aring-like iframe carrying reticulated material which is received in theouter ring-like member and is adapted to admit ventilation through thedevice and prevent the entrance of insects therethrough, means on theringlike members for retaining sai-d frame firmly in position, andadditional means on the outer member adapted to tighten the peripheralportion of said frame Vin the re-V ceiving ring.

rlfhe invention is satisfactorily illustrated in the accompanying`drawing, but the important instrumentalities thereof may be varied, andso it is to be understood that the invention is not limited to thespecific details shown and described, as long as they are within thespirit or scope of the claims.

Figure 1 represents a front elevation of a port light embodying myinvention.

Fig. 2 represents a rear view thereof.

Fig. 3 represents a rear view of the eX- terior member of the device.

Fig. 4 represents a diametrical section of the reticulated member of thedevice.

Fig. 5 represents a diametrical section on line 5-5 Fig. 2.

Fig. 6 represents a diametrical section on line 6-6 Fig. 2, includingcertain portions of the place of application of the device.

Fig. 7 represents a diametrical section of portions of the members ofthe device in separated condition. Y Figs. 8 and 9 represent otherembodiments of the invention.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings. f

1 designates the exterior member of the device, the same consisting of aring having on its front portion the outturned bead 2, and the inturnedrim or flange 3.

4 designates a ring-like frame to which the peripheral portion of thepiece 5 of Specification of LettersPatent.

gauze or other reticulated` materialV is secured, said frame beingseated against the flange 3 and so prevented from being displacedoutwardly.

In order to hold said frame 4 in position on the flange 3 there aresecured to the inner e face of the ring member 1 the inturned lugs 6whose outer ends are adapted to contact with the outer periphery of theframe 4 at intervals and grip tightly against the same whereby saidframe 4 is prevented from rotation.

7 designates the inner member of the device, the same consisting of aring having on its front portion the outturned flange 8, and on itsrearv portion the inturned flange 9, the diameter of said member 7 beingslightly less than the diameter of the member 1, it being noticed saidmember 7 is adapted to enter the member 1 concentric therewith. Then theflange 8 bears against the frame 4 of the reticulated material and holdsthe sameV against inward motion and displacement while the flange 9contacts with and overlaps the inner edge of the member' 1 and forms avclose joint therewith and correctly positions thev member 7 forsubsequent locking of the two members as will now be described.

On the inner face of the member 1 are the inturned studs 10 atintervals. In the member 7 are the Lshaped slots 11 at intervals adaptedto receive said studs forming bayonet-joints Yfor connecting the twomembers, it being evident that when the studs enter the receivingportions of said slots, the member 7 is turned when said studs ride intothe other portions of said slots and so the members are locked as mostplainly shown in Fig. 5, a feature not new per se.

When, however, the member 7 is turned in reverse direction, the studsare in communi cation with the receivingk portions of the slots 11, thensaid member 7 may be drawn out of the member 1 and entirely removedtherefrom when so required.

On the inner side of the member 7 are the thumb or finger piecesv 12 forconvenience or" turning or rotating the member 7.

In Fig. 6 is shown the collar 13 on the side of a ship or other place ofservice of the port light, the same being connected with said side orplace by the bolts 14, and nuts thereon or other suitable means, itbeing noticed that the device is adapted to be ttted in said collar fromwithout, when rections on the collar 13, and soV remainingv reliably inits applied position.

In order to hold the device tightly in the collar 13 there are securedto the exterior of the side of the outer ring 1 the resilient tongues15, see Figs. 5, 7, 8 and 9, which project outwardly from said side andare adapted to enter said collar 13 and engage the inner face thereof,and press against theV same, as most plainly shown in Fig. 9, while alsobeing resilient 1n their nature,

and providing cushions which take up any strain or shocks on the portlight.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, isc- Y 1. In a port light, inner and outerring members, a reticulated material in the outer member, and meansadapted to connect said members, the outer ring member having aninturned rim on which the peripheral frame of said reticulated materialis adapted to be seated, the inner ring member having in front aninterned rim which is adapted to bear against said frame, and at therear an outturned flange which is adapted to overlappingly engage theinner edge of the outer 4ring member.

2. In a port light, inner and outer ring members, a reticulated materialin the outer member, and means adapted to connect said member, the outerring member having an inturned rim on Which the peripheral frame of saidreticulated material is adapted to be seated, the inner ring memberhaving in front an inturned rim which is adapted to bear against saidframe,rand at the rear an outturned flange which is adapted tooverlappinglyengage theinner edge ofthe outer ring member, said outerring member having also in front an outturned bead which j is continuouswith the inturned rim on said member.

3. In a port light, inner and outer ringV terial, means on the innerring adapted to4 engage said frame and resilient cushions on the outerside of the outer ring.
